BOOKBINDING.

Application filed November 18, 1924. Serial No. 750,576.

To all whom it may; cam-em:

Be it known that I, GHARLEs L. AsAM, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented a new and useful Bookbinding, of which the following is a specification.

My invention relates to books, and it has particular relation to the bindings thereof.

One object of my invention is to provide a sample book which shall be adapted to withstand a considerable amount of use and still maintain the sheets in satisfactory form.

Another object of my invention is to provide an improved form of binding for sample books which minimizes the tendency for the sheets to tear immediately adjacent to the binding.

A further object of my invention is to provide a sample book, wherein the binding is of uniform thickness regardless of the width of the individual sheets.

Other objects and applications and advantages of my invention, as well as details of construction and arrangement, whereby my invention may be practiced, will appear more fully hereinafter, when taken in connection with the accompanying drawing, wherein- Fig. 1 is a perspective view of one form of embodiment of my invention, with the book partially opened;

Figs. 2 and 3 are side and end elevational views of the structure of Fig. 1 but showing the book closed; and

Fig. 4 is an inverted perspective view of the compensating Wedge shown in Figs. 1 to 3.

In the drawing, by invention is illustrated in connection with a wall paper sample book 1 of usual form, though of course, it is not to be strictly limited to display books of this type. The book 1 thereinshown comprises a plurality of sheets 2 and 3 of different width, corresponding ends 4 of which are secured together by means of a binding 5. The latter may include wire staples 6 or other fastening means known to the art.

Inasmuch as the relatively narrow sheets 3 do not extend the full width of the binding 5, the latter is considerably thicker on one side than the other. As above-noted, my invention contemplates means, whereby the uneven thickness of the binding may be p t d, Said means a s serv g to minimize the tendency of the sheets 2 and 3 to tear immediately, adjacent to the binding 5. To this end,-I provide a wedge 7 of pasteboard or other suitable material, which is adapted to be imbedded in the binding 5, as illustrated in Figs. 2 and 3.

The wedge 7 comprises an elongated substantially fiat strip 8 having opposite side edges 9 and 10 and end edges 11 and 12. As

shown in Fig. 4, the edges 10 and 12 are re spectively beveled to provide surfaces 13 and 14. The wedge 7 is mounted in the binding 2.

5 in such manner that the end edge 11 and the side edge 9 are respectively in alignment with the end and side edges of the sheets 2 and 3, while the edges 10 and 12 are disposed within the binding 5.

While I have shown only one form of embodiment of my invention, for the purpose of describing the same and illustrating its principles of construction, it is apparent that various changes and modifications may be made therein without departing' from the spirit of my invention, and I desire, therefore, that only such limitations shall be imposed thereon as are indicated in the appended claims or as are demanded by the prior art.

I claim:

1. A book comprising a plurality of sheets of different width having corresponding ends bound, and means so iming bound together, and a wedge so disposed in the binding as to compensate for theincreased thickness thereof due to the relatively narrow sheets.

4. A book comprising a plurality of sheets of different width, means for binding corresponding ends of said sheets, and a wedge so associated with said binding as to compensate for the'increased thickness of one portion of the binding due to the rela,

tively narrow sheets, said wedge having beveled surfaces,

5. A sample book comprising a plurality of sheets of different Width bound on corre sponding ends thereof, and a Wedge so associated with the binding as to compensate for the increased thickness of one portion of the binding due to the relatively narrow sheets certain of the upper edges of said Wedge being beveled.

6. A sample book comprising a plurality of sheets of different Width, means for binding corresponding ends ofsaid plurality of sheets, and a Wedge so associated with said binding as to compensate for the increased thickness of one portion thereof due to the relatively narrow sheets-said Wedge comprising an elongated strip having the surface adjacent to one end and side beveled.

T. A compensating Wedge for bindings comprising an elongated strip having the surface adjacent to one side beveled.

8. A compensating Wedge for the binding of a sample book employing sheets of different Width, comprising a substantially flat elongated strip, portions of the upper surface thereof adjacent to transversely extending edges being beveled.
